DETAILED DESCRIPTION

[0036] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0037] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0038] Example 1, as Figures 1-14 As shown, a tomato leafminer larvae cultivation device according to an embodiment of the present application includes a cultivation tube 1 and a cultivation portion 3. A central shaft 2 is coaxially arranged in the cultivation tube 1, and a driving component 11 for providing power to the central shaft 2 is arranged at the bottom of the cultivation tube 1. Figure 3-Figure 5As shown, the drive assembly 11 includes a barrel 111, a drive shaft 112, a spur gear pair 113, a manual rotating shaft 114 and a bevel gear pair 115. The barrel 111 is fixed to the inner bottom of the cultivation cylinder 1; one end of the drive shaft 112 is connected to the spring, and the other end of the drive shaft 112 extends out of the barrel 111; the spur gear pair 113 is composed of two gears combined with each other, and the two gears are fixedly mounted on the drive shaft 112 and the center shaft 2 respectively; the manual rotating shaft 114 is arranged along the radial direction of the cultivation cylinder 1, and one end thereof extends out of the cultivation cylinder 1; the bevel gear pair 115 is composed of two bevel gears meshing with each other, and the two bevel gears are respectively mounted on the drive shaft 112 and the manual rotating shaft 114.

[0039] It can be understood that the staff can rotate the drive shaft 112 by rotating the manual shaft 114 and tighten the spring in the spring box 111. After releasing the hand, the drive shaft 112 will continue to rotate under the action of the spring elastic force to reset, which will drive the center shaft 2 to rotate continuously. The specific rotation time is determined by the spring, and the specific rotation speed can be determined by the size of the two gears in the spur gear pair 113. It is only necessary to explain here that the gear on the drive shaft 112 is smaller than the gear on the center shaft 2. In this way, the rotation speed of the center shaft 2 can be reduced.

[0040] like Figure 2-Figure 4 、 Figure 6-Figure 8 As shown, the cultivation part 3 includes a water storage tank 31, a breeding area 32, a water supply component 33, a plurality of connecting pipes 34 and a power component 35. The water storage tank 31 is arranged in an annular shape and is used to store part of the water body to provide water to the breeding area 32; the breeding area 32 is covered on the top side of the water storage tank 31; the water supply component 33 is coaxially sleeved on the central axis 2, and the water supply component 33 is divided into a fixed part and a movable part. The water source is stored in the fixed part, wherein the inner top of the fixed part is higher than the inner bottom end of the water storage tank 31, and the movable part undergoes elastic lifting and lowering action in the fixed part; a plurality of connecting pipes 34 are uniformly connected to the water supply component 33 in the circumferential direction, and the plurality of connecting pipes 34 are respectively It is connected to the water tank 31 so that the water stored in the fixed part of the water supply component 33 can flow into the water tank 31; the power component 35 includes a passive wedge column 351 connected to the movable part of the water supply component 33, and an active wedge column 352 fixedly sleeved on the central shaft 2. The passive wedge column 351 is movably sleeved on the central shaft 2. The central shaft 2 drives the active wedge column 352 to rotate by rotating, and drives the passive wedge column 351 to drive the movable part of the water supply component 33 to perform reciprocating lifting and lowering movements. Through the reciprocating lifting and lowering movement of the movable part, the water source in the fixed part can enter the water tank 31 through the connecting pipe 34.

[0041] Specifically, the breeding area 32 includes an annular baffle 321, multiple connecting strips 322, a fence 323, multiple breeding nets 324, multiple water suction pipes 325 and a water supply pipe 326. The annular baffle 321 is sealed and covered on the top of the water storage tank 31 to prevent the evaporation of water therein, which causes the water source to decrease rapidly, and at the same time prevents the humidity inside the culture tube 1 from being difficult to control due to the evaporation of water. The multiple connecting strips 322 are arranged on the inner side of the annular baffle 321 along the radial circumferential direction and are movably sleeved on the central axis 2. It should be noted that, as shown in FIG. Figure 4 As shown, the design of the connecting strip 322 creates a hollow state in the middle of the breeding area 32; the enclosure 323 is coaxially arranged on the top side of the annular baffle 321 and movably sleeved on the central axis 2; multiple breeding nets 324 are embedded one by one in the enclosure 323 and abut against the connecting strip 322; multiple water suction pipes 325 are circumferentially arranged on the annular baffle 321 and extend into the water storage tank 31; the water supply pipe 326 is inserted into the annular baffle 321 and extends into the water storage tank 31 for replenishing the water source.

[0042] It should be noted that if Figure 4 As shown, the periphery of the enclosure 323 is arranged in a ring shape, and a plurality of straight partitions radiate from the interior of the ring. The plurality of straight partitions divide the interior of the enclosure 323 into a plurality of sector-shaped areas, and a plurality of feeding nets 324 are embedded in the plurality of sector-shaped areas in a one-to-one correspondence.

[0043] It can be understood that the enclosure 323 can form a fence around each breeding net 324 to prevent the larvae on adjacent breeding nets 324 from forming a "jailbreak" state, thereby improving the observation effect of the larvae on each breeding net 324.

[0044] It is further necessary to explain that if Figure 4 and Figure 8 As shown, a capillary water channel 327 is provided on the upper side of the connecting strip 322 for supplying water to the blades placed on the breeding net 324; a plurality of flow channels 328 are provided on the annular baffle 321, and the plurality of flow channels 328 are respectively connected to the plurality of capillary water channels 327; the water suction pipe 325 is hollow (its bottom end adopts a hollow design and a detachable end cap is provided on the top), which is filled with a water-absorbing resin, and the water suction pipe 325 is located on the side wall of one end of the top side of the annular baffle 321 and has a plurality of water outlets 329 distributed in a fan shape, and the plurality of water outlets 329 are connected to the diversion water channels 328 in a one-to-one correspondence.

[0045] From this, it can be understood that when the water level in the water storage tank 31 rises to a height exceeding the bottom end of the water suction pipe 325, the water-absorbing resin absorbs the water and supplies water to the capillary waterway 327 through the water outlet 329 and the diverter waterway 328. It should be noted that the water outlet 329, the diverter waterway 328, and the capillary waterway 327 all utilize capillary action to achieve water transmission.

[0046] like Figure 10 As shown, the water supply pipe 326 is double-layered, and a through hole is provided at the bottom end of the double layer of the water supply pipe 326. The height of the inner layer of the water supply pipe 326 is greater than the height of the outer layer. A sealing cap is provided on the inner layer of the water supply pipe 326, and the sealing cap is used to seal the cavity between the inner and outer layers of the water supply pipe 326.

[0047] It should be noted that the double-layer design, with one layer being closable, facilitates balancing the internal air pressure of the water storage tank 31 during the water replenishment process.

[0048] It should be further explained that the water supply assembly 33 includes a piston cylinder 331, a piston 332 and a plurality of connecting rods 333. The piston cylinder 331 is the fixed end of the water supply assembly 33, and the piston cylinder 331 is movably mounted on the central axis 2; the piston 332 is the movable end of the water supply assembly 33 and is sealed and slidable on the piston cylinder 331; a plurality of connecting rods 333 are circumferentially fixed to the piston 332 and extend out of the piston cylinder 331 in a sealed manner, and a plurality of connecting rods 333 are fixed to the passive wedge column 351; a spring is mounted on the connecting rod 333 (not shown in the figure, only as a reset effect of the piston 332, and is not limited to the use of only the spring or the installation position of related components), and the two ends of the spring are respectively abutted against the piston cylinder 331 and the passive wedge column 351.

[0049] It should be noted that the ends where the passive wedge-shaped column 351 and the active wedge-shaped column 352 abut against each other are smooth inclined surfaces that fit together.

[0050] It can be understood that when the central shaft 2 is powered by the driving component 11 and rotates, it will drive the active wedge column 352 fixed thereon to rotate, which will force the passive wedge column 351 to drive the piston 332 to rise in the piston cylinder 331 through the connecting rod 333. Under the reset action of the spring, the piston 332 will fall after rising to the highest point. In this way, when the central shaft 2 continues to rotate, the piston 332 will reciprocate and rise in the piston cylinder 331. It can be further understood that when the piston 332 reciprocates and rises, the water source in the piston cylinder 331 will generate a tidal phenomenon in the water tank 31 through the connecting pipe 34, that is, the water level in the water tank 31 will repeatedly rise and fall. Combined with the water suction pipe 325 mentioned above, the blade direction will be intermittently replenished with water to prevent the blades from drying out.

[0051] It should be noted that in the embodiment of the present application, the connecting tube 34 is arranged in an arc shape, one end of the connecting tube 34 is connected to the top end of the side wall of the piston cylinder 331, and the other end of the connecting tube 34 is connected to the bottom end of the side wall of the water storage tank 31.

[0052] It can be understood that when the water flows in the connecting pipe 34, under the action of the arc-shaped guide, it will form a certain impact on the water tank 31 and the piston cylinder 331 at both ends, preventing impurities from forming precipitation inside the water tank 31 and the piston cylinder 331, and at the same time preventing precipitation from causing blockage in the connecting pipe 34. Furthermore, after the water enters the water tank 31, the arc-shaped connecting pipe 34 causes the water to rotate to a certain extent in the water tank 31, thereby ensuring the water absorption effect of multiple water suction pipes 325 in the water tank 31 (avoiding the situation where the local water suction pipe 325 cannot absorb water when the entire cultivation cylinder 1 is tilted at a certain angle).

[0053] Among them, a boss is provided at the top of the piston 332, and a plurality of spiral grooves 334 are evenly arranged on the side wall of the boss. It can be understood that when the piston 332 is raised and lowered, the spiral grooves 334 cause the water in the piston cylinder 331 to further rotate, thereby enhancing the flushing effect on the inner wall of the piston cylinder 331 and the piston 332.

[0054] It should be noted that a bracket 335 is provided on the bottom side of the piston cylinder 331 and the water storage tank 31, and the bracket 335 is movably sleeved on the central axis 2, wherein a plurality of limiting grooves 12 are evenly arranged circumferentially on the inner wall of the cultivation cylinder 1, and the bracket 335 and the limiting grooves 12 are slidably matched to facilitate the installation and disassembly of the entire cultivation part 3 in the cultivation cylinder 1.

[0055] Among them, a guide top 336 is coaxially arranged on the top of the piston cylinder 331, and the guide top 336 is coaxially movably sleeved on the central axis 2. The guide top 336 is conical with a small top and a large bottom. It can be understood that this design can prevent the insect feces falling from the top side from accumulating above the piston cylinder 331, affecting the quality of the internal environment of the entire cultivation cylinder 1.

[0056] The following describes the use of a tomato leafminer larvae cultivation device according to an embodiment of the present application with reference to the accompanying drawings:

[0057] When in use, the leaves are placed on multiple breeding nets 324 respectively, and the larvae are placed on the corresponding leaves respectively. The independent breeding nets 324 form an independent breeding space, which can avoid the larvae in a breeding space from being too dense, resulting in uneven development of the insect body and the appearance of size differences. After placing the larvae, according to observation, the staff can rotate the manual rotating shaft 114 when the humidity inside the cultivation cylinder 1 or the humidity of the leaves is not enough, so that the central shaft 2 rotates for a certain period of time, and the rotation of the central shaft 2 is used to make the piston 332 rise and fall back in the piston cylinder 331 (the lifting speed is controlled by the speed of the central shaft 2, and the specific transmission ratio and other related parameters are not repeated here). The water in the piston cylinder 331 enters the water storage tank 31 through the connecting pipe 34 under the rising action of the piston 332. As the piston 332 rises, the water storage tank 3 325 , the water level in the water tank 31 gradually rises and exceeds the height of the bottom end of the water suction pipe 325. At this time, the water-absorbing resin in the water suction pipe 325 absorbs the water and, through capillary action, allows the water to enter the capillary water channel 327 from the water outlet 329 and the diverter water channel 328, providing a certain degree of water to the blades on the breeding net 324. Conversely, when the piston 332 descends, a negative pressure is formed in the piston cylinder 331, causing the water in the water storage tank 31 to be sucked back into the piston cylinder 331 through the connecting pipe 34. At this time, the water level in the water storage tank 31 drops or even disappears. At this time, the water suction pipe 325 cannot provide water to the blades. This design makes the water supply to the blades form a tidal water supply phenomenon, and provides water from the bottom side of the blades, avoiding the impact on the insects caused by spraying water from above the blades, the drastic changes in the humidity of the breeding environment, and the tediousness of frequent manual water spraying.

[0058] In the related art, in a tomato leafminer larvae cultivation device, during the breeding process, the insects will produce a large amount of feces as they grow. Although a breeding net 324 and a hollow design in the breeding area 32 are adopted, a certain amount of feces will still remain on the leaves. The residual feces will breed mold if they stay in the breeding environment (with a certain humidity) for a long time, posing a great threat to the healthy growth of the insects and affecting the normal observation of larval breeding.

[0059] Example 2: According to some embodiments of this application, Figure 2 、 Figure 3 、 Figure 12 and Figure 13 As shown, a guide part 4 is also provided in the cultivation tube 1, and the guide part 4 includes a spiral slide 41 and a vibration part. The spiral slide 41 is coaxially arranged on the bottom side of the cultivation part 3, and is used to guide the insect feces dropped from the cultivation part 3 to a specified direction; the vibration part is coaxially arranged on the top of the cultivation part 3, and is used to provide regular vibration to the cultivation part 3.

[0060] Specifically, side guards 411 are provided on both sides of the spiral slide 41. The radial range of the spiral slide 41 covers the breeding range of the breeding area 32. The side guards 411 are used to prevent the insect feces from bouncing when falling on the spiral slide 41, thereby preventing the insect feces from falling to the non-specified position at the bottom of the breeding tube 1.

[0061] Specifically, a plurality of positioning rings 412 are axially arranged on the circumference of the spiral slide 41 . The plurality of positioning rings 412 and the inner wall of the cultivation cylinder 1 are slidingly matched with each other. A positioning bar 413 is fixed between the positioning rings 412 and the spiral slide 41 .

[0062] It should be noted that the vibration part includes a ring 42, a swivel 43 and a plurality of elastic rods 44. The ring 42 is coaxially fixed to the top of the enclosure 323. A plurality of extension plates 421 are evenly fixed to the circumference of the ring 42. The plurality of extension plates 421 are distributed along the straight partitions on the inner side of the enclosure 323 and correspond one-to-one to the straight partitions; the swivel 43 is coaxially fixed to the central axis 2; a plurality of elastic rods 44 are damped and slidably inserted into the swivel 43, and the elastic rods 44 are arranged along the axial direction of the swivel 43 and are in elastic contact with the extension plates 421.

[0063] It can be understood that in the present application, since there is a damping sliding relationship between the elastic rod 44 and the rotating ring 43, the axial position of the elastic rod 44 on the rotating ring 43 can be adjusted. It can be further understood that when the bottom end height of the elastic rod 44 decreases, the force of the elastic collision between it and the extension plate 421 becomes greater, and vice versa.

[0064] It should be noted that in the specific embodiment of the present application, a partition is provided on the inner bottom of the cultivation cylinder 1 above the clockwork box 111, and a collecting bucket 14 is slidably provided on the partition, and a side sliding door 15 is provided on the side wall of the cultivation cylinder 1. The collecting bucket 14 can be taken out from the side sliding door 15. The collecting bucket 14 is located below the outlet end of the spiral slide 41 and is used to collect the guided insect feces.

[0065] Therefore, when in use, the rotation of the central shaft 2 will also drive the rotating ring 43 to rotate synchronously, so that the multiple elastic rods 44 thereon will come into contact with the extension plate 421, that is, the elastic rods 44 will be deformed by the obstruction of the extension plate 421 when following the rotation. As the rotation continues, the bottom end of the deformed elastic rod 44 will slip out of the gap between the rotating ring 43 and the extension plate 421 and reset. Under the action of reset and rotation, it will cause an impact on the side wall of the next extension plate 421, which will cause a knock on the collar 42. And it is transmitted to the breeding net 324 through the enclosure 323, causing the blades on it to vibrate, which will reduce the insect feces that may remain on the blades and the breeding net 324. Of course, the specific radial position and axial length of the elastic rod 44 on the rotating ring 43 can be adaptively changed to form irregular vibrations, avoiding resonance and causing increased amplitude to cause damage to the larvae. The fallen insect feces will be guided by the spiral slide 41 and slide into the collection bucket 14 below. The staff can regularly open the side sliding door 15 to clean the dirt in the collection bucket 14.

[0066] In the related art, a device for cultivating tomato leafminer larvae requires watering the leaves in its breeding environment, which will cause a certain humidity in the breeding environment. If the humidity exceeds the safe value, mold will grow on the leaves, affecting the health of the larvae. However, if the humidity drops seriously in order to drain moisture, the leaves will be frequently watered, wasting water.

[0067] Example 3: According to some embodiments of this application, Figure 2 、 Figure 3 and Figure 14 As shown, a ventilation portion 5 is further provided inside and at the top of the cultivation cylinder 1, wherein the ventilation portion 5 includes a guide tube 51, which is coaxially embedded in the inner side of the spiral slide 41, and its axial ends extend out of the top and bottom sides of the spiral slide 41 respectively; an air flow guide component 52 is circumferentially distributed around the cultivation cylinder 1, and the air flow guide component 52 connects the water storage tank 31 and the guide tube 51; and an air outlet end 53 is provided at the top of the cultivation cylinder 1.

[0068] Specifically, the airflow guide assembly 52 includes multiple guide tubes 521 and a floating ring 522. One end of the multiple guide tubes 521 is inserted into the annular baffle 321, and the other end of the multiple guide tubes 521 extends to the inner bottom of the guide tube 51; the floating ring 522 is sealed and limited and slides on the water tank 31 to prevent the floating ring 522 from falling to the bottom of the water tank 31; the water suction pipe 325 and the water supply pipe 326 are respectively sealed and slidably inserted into the floating ring 522.

[0069] Specifically, the top of the cultivation tube 1 is provided with a tube cap 13, and the tube cap 13 is provided with a mounting groove 131; the air outlet end 53 includes an axial fixing block 531, a plurality of support bars 532, a plurality of bottom side blades 533 and a plurality of top side blades 534, the axial fixing block 531 is coaxially embedded in the mounting groove 131; a plurality of support bars 532 are evenly fixed to the axial fixing block 531 in the circumferential direction, and a plurality of support bars 532 are embedded in the mounting groove 131; a plurality of bottom side blades 533 are evenly arranged in the circumferential direction in the mounting groove 131, and One end of the bottom side blade 533 rotates on the side wall of the mounting groove 131, and the other end of the bottom side blade 533 is rotatably connected to the side wall of the axis fixing block 531; multiple top side blades 534 are evenly arranged circumferentially on the mounting groove 131, and one end of the top side blade 534 rotates on the side wall of the mounting groove 131, and the other end of the bottom side blade 533 is rotatably connected to the side wall of the axis fixing block 531; multiple bottom side blades 533 and multiple top side blades 534 are matched one by one, and the top side blades 534 are crimped to the bottom side blades 533.

[0070] It should be noted that only parts of the top blade 534 and the bottom blade 533 overlap during the crimping operation.

[0071] It should be further explained that when the top blade 534 is pressed against the bottom blade 533 , a gap is left between the two to ensure the air (oxygen content) required for normal cultivation inside the culture tube 1 .

[0072] Therefore, during actual use, when the piston 332 rises in the piston cylinder 331, the water source rushes into the water tank 31. As the water level rises, the floating ring 522 rises in the water tank 31. At this time, the air above the floating ring 522 in the water tank 31 is compressed and flows through the guide tube 521 to form an air flow that rushes to the bottom of the guide cylinder 51. The air flow is guided by the guide cylinder 51 and flows out from the top, that is, from the bottom of the piston cylinder 331. Under the action of air pressure conservation, the air flow will pass through the hollow area in the middle of the breeding area 32, that is, the breeding net 324, and then rush to the top of the breeding cylinder 1, so that the top side blades 534 and the bottom blades 534 that were originally pressed together are The side blades 533 rotate and form an open state, and the air flows from here to the outside. Conversely, when the piston 332 descends, a negative pressure is formed in the water storage tank 31, causing the outside air to be sucked into the interior of the cultivation tube 1 and transported to the interior of the water storage tank 31 through the guide tube 521. At this time, a pressure connection is formed between the top side blades 534 and the bottom side blades 533 (but not sealed). This design will form airflow inside the entire cultivation tube 1 and create a ventilation effect inside the cultivation tube 1, which will ensure the freshness and humidity of the air inside the cultivation tube 1 and reduce the negative conditions such as the formation of mold in the cultivation environment that are not conducive to the growth of larvae.

[0073] In order to facilitate observation and normal cultivation of larvae, some parts such as the cultivation tube 1, the water storage tank 31, the connecting pipe 34, the piston cylinder 331 can be made of transparent materials to facilitate light exposure and observation of water reserve.

[0074] It should be noted that the specific models and specifications of the barrel 111, the spur gear pair 113, the bevel gear pair 115, the piston 332 and the elastic rod 44 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field and will not be described in detail.

[0075] The above are only specific embodiments of the present application, but the scope of protection of this application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
